CHARLOTTE, North Carolina — The Panthers say coach Ron Rivera plans to be at Wofford College on Thursday when players report to training camp, but could miss some practices following the death of his brother.

Rivera posted on Twitter that his brother Mickey, 56, died on Wednesday following a two-year battle with pancreatic cancer. Mickey Rivera lived in Reno, Nevada.

Panthers spokesman Steven Drummond says Rivera's plans remain fluid because funeral arrangements are still being finalized. The Panthers start practice Friday and their first day off isn't until Tuesday.

Rivera also posted a picture of he and Mickey on Twitter and wrote, "He was one of my 1st & best teammates. Love u bro."

The coach presented his brother with a game ball after Carolina's playoff win against Arizona in January.
